Hanauma Bay is a protected marine life conservation area and an underwater park.It’s bay floor is the crater of an ancient volcano that lost its exterior wall which allowed the ocean to rush in.Making it a curved looking beach.It consists of a variety of marine life. There are many reefs in the bay, barely any waves, and no predators. The beach/grassy side of the area, also contains several types of land animals.There are even a various amount of birds here and there.This site will be a god place to study for the rest of the semester, because it is safe and protected, and it’s diverse life on land and sea.

Hanauma Bay, consists of several organisms and niches.The Bay consists of a variety of reef marine life such as the racoon butterflyfish, reef triggerfish, and sea urchins. And on land many mongooses, and cats are found around the grassy/bushy areas of the bay.Birds, are scattered all around the bay and sky.The raccoon butterfly fish is a nocturnal feeder, while still active in the day.It habits among the reef or rocky areas of the bay.The reef triggerfish habits among the reefs, using it for cover, and shelter.It eats mostly reef invertebrates and algae.However, at times it may eat other smaller fishes.

The water in the bay is salt water.The bay consists of a variety of reefs.Towards the left side, it seems there is more reef than the further you go right.A quarter of Hawaii’s endemic marine animals live in the waters of Hanauma Bay.The shallow waters contain most of the reef species.So the further you go down the bay is, there a significant difference in the marine life? What abiotic factors may affect this?On land it seems the mongooses and cats come only because of the things people are putting out, such as trash cans, and food.Is the trash and food attracting these animals?How does the sand affect the animals and their niches, that are living here?

Hanauma Bay, is an environment that mostly consists of a symbiosis.All the marine species in the water all live with one another.Some help each other, some don’t.For example, lets say a humumu eat another small fish.On the other hand, we have coral that is a symbiosis itself.However, most of the animals all use the coral and reef for a safe place to live.Even on land I saw cats, and mongooses that use the bushes that are there to hide and probably to avoid predators, or for shelter.

The sand affects the life in Hanauma Bay on land, by not allowing any plant life/vegitation to grow on it.Allowing certain marine animals such as crabs to come up onto these beaches and live.So if there were no sand on land, then the beach would change dramatically, because the plants may grow up till the water and perhaps even effect the marine life.The trash and food probably do affect the cats and mongooses that come here.So does the cliff, and the plants.But the trash and food attract them onto the beach, probably because it’s a easy way to get food.I even saw a mongoose digging in the trash once, probably looking for food.So if their were no trash, then there would be no cats or mongooses, in Hanauma Bay, because their would be no food for them there.I think the locations in Haunama Bay do have an effect on what or how many fishes live there.So if the ph levels are lower then there will be more fishes living there, also on how much reef there are in each section. When I went on Sunday 11/23/08 at 2:00 P.M.All the observations I had last time remained the same.However this time I collected PH and temperature levels.So area 1 (to the far left of the bay) had a temperature of 70 degrees in the air, and was 64 degrees in the water.The water in that area had a ph level of 4.In area 2 (in the middle of the bay) had an outside temperature of 71 degrees and the water had a temperature of 65 degrees.The ph of thewater was 5.In area 3 (on the far right side of the bay) the outside temperature was 72 degrees and 67 degrees in the water, the ph of the water was 4.
Assigned Journal #3 One big environmental pressure that could be driving Natural Selection in Hanauma Bay are people.Even though Hanauma Bay is a nature life preserve park, people are still allowed in.And some people that go in the water may no listen to the “do not fee rule.”Therefore, maybe, slowly, Natural Selection is taking place, because some fish may not hunt for food as often.Affecting their ways of life.Also, perhaps even the appearance of people, in some way is driving the lives of species in Haunama Bay.
Free Journal Some observations I made were the types of fishes that were in the bay.They had species such as uhu (parrotfish), vana (sea urchin), nunu (tumpetfish), kikapau & lau wiliwili (butterflyfish), and humuhumu (triggerfish).In area one there is much more reef than the other areas.In area 2 there is some reef, but not as much as area 1.And on in area 3, there is barely any reef, but has a lot of rocky structures. My experiment is to test if the abiotic factors in the reefs have visible effects on the fishes that live there.So far I know to the far left of the bay (area 1) is 64 degrees in the water, in the afternoon, and has a ph lever of 4.At the middle of the bay (area 2) is 65 degrees in the water, in the afternoon, and it has a ph level of 5.And in the far right of the bay (area 3) has a temperature of 65 degrees in water, and has a ph of 4.My procedures consist of swimming in straight lines out into the ocean in each area.I will use underwater paper to jot down the type of fish I see and how much of them, in each of the lines I swim in.I will repeat the same experiment for all three areas.

From this data I can conclude that my hypothesis was correct.There were more fish where reefs, and rocks were more plentiful.Also in the area where the ph level of the water was 5, there were less fish there.All in all, to the far left of the bay has the most fish, because it has a low ph, and it is where reef and rocks are most plentiful.To the middle of the bay has the least marine life, because its ph is 1 higher than the other two spots, and there is barely any reef and rocks in that area.Now, to the far right of the bay, the marine life is more than the ones in the middle, but less than the far left.This is because even though it has a low ph level, there is not that much reef, but more rocks, which is why there are a lot of vana that were easy to spot.

The sand affects the life in Hanauma Bay on land, by not allowing any plant life/vegitation to grow on it. Allowing certain marine animals such as crabs to come up onto these beaches and live. So if there were no sand on land, then the beach would change dramatically, because the plants may grow up till the water and perhaps even effect the marine life. The trash and food probably do affect the cats and mongooses that come here. So does the cliff, and the plants. But the trash and food attract them onto the beach, probably because it’s a easy way to get food. I even saw a mongoose digging in the trash once, probably looking for food. So if their were no trash, then there would be no cats or mongooses, in Hanauma Bay, because their would be no food for them there. I think the locations in Haunama Bay do have an effect on what or how many fishes live there. So if the ph levels are lower then there will be more fishes living there, also on how much reef there are in each section. When I went on Sunday 11/23/08 at 2:00 P.M.

One big environmental pressure that could be driving Natural Selection in Hanauma Bay are people. Even though Hanauma Bay is a nature life preserve park, people are still allowed in. And some people that go in the water may no listen to the “do not fee rule.” Therefore, maybe, slowly, Natural Selection is taking place, because some fish may not hunt for food as often. Affecting their ways of life. Also, perhaps even the appearance of people, in some way is driving the lives of species in Haunama Bay.
